If you own an aerobic treatment unit in Florida and you have been reading advice written for Texas, almost none of it applies to you. The machine in your yard is the same. The legal structure around it is not, and the differences are the kind that cost money: a permit Texas owners do not have, an inspection schedule that is set differently, and one route Florida offers that Texas largely does not.
This guide covers what Florida actually requires, who to talk to, and the question most owners get wrong before they even start.
Comparing states, or moving between them? Our state-by-state comparison of aerobic septic rules puts all four side by side.
First, the thing almost every article about Florida septic gets wrong
Search for Florida septic rules and you will be told to contact the Florida Department of Health. That was correct until 2021, and it is now, at best, half right.
Florida’s onsite sewage program transferred from the Department of Health to the Department of Environmental Protection, effective 1 July 2021, under Senate Bill 712 of the 2020 session, signed as Chapter 2020-150, Laws of Florida.
But the day-to-day did not move with it. Under an interagency agreement, county health department staff continued performing permitting, inspections, data management and tracking on DEP’s behalf. So for most owners, the office you deal with is still the county health department, even though the agency responsible is DEP.
Then it changed again. From 2 January 2025, DEP began managing septic permitting directly in 16 Panhandle counties:
Bay, Calhoun, Escambia, Franklin, Gadsden, Gulf, Holmes, Jackson, Jefferson, Leon, Liberty, Okaloosa, Santa Rosa, Wakulla, Walton and Washington. Marion County also transferred to DEP on July 1, 2025, bringing the directly managed group to 17 counties.
If your county is on that list, you deal with DEP. If it is not, you contact your county health department. Getting this right before you pick up the phone saves a wasted call and, more importantly, tells you whose answer is authoritative.
The operating permit Texas owners do not have
This is the single biggest structural difference, and it surprises owners moving from other states.
In Florida, an aerobic treatment unit requires an operating permit that must be kept valid for the life of the system, and it is renewed every two years. It is not a one-off construction approval you file away. It is an ongoing licence to operate the thing in your yard.
And it comes with a condition that catches people out: the operating permit will not be issued unless a current maintenance agreement is in effect. The permit and the contract are locked together. Let the contract lapse and you are not merely unmaintained, you are at risk of being unpermitted.
The maintenance entity, and what it must do
Florida does not simply require “a qualified provider”. It requires an approved maintenance entity: a person or business that has been issued a written permit by the department to provide maintenance services for approved aerobic treatment units.
The obligations that follow are specific:
- A valid maintenance contract for the life of the system. Not for a fixed initial period after which you are free.
- On new construction, the first contract runs two years. Renewals must then be for terms of at least one year.
- The maintenance entity must inspect or service the unit at least twice each year.
- A copy of the maintenance agreement goes to the regulator. It is not a private arrangement between you and a contractor.
Compare that with Texas, where the rule is built around reporting frequency rather than visit count: a report to the permitting authority and the owner at least every four months, dropping to six months only where the system has electronic monitoring. Our guide to Texas maintenance contracts covers that structure in detail.
The route Florida offers that most owners never hear about
Here is the provision worth knowing, because almost nobody will volunteer it to you.
In Florida, a property owner may qualify to be permitted as the maintenance entity for their own aerobic treatment unit, serving their owner-occupied single-family residence. Two conditions apply: you must comply with all the provisions of the rule governing aerobic treatment units, and you must hold written approval from the manufacturer certifying that you have received training on servicing your unit.
Read both conditions carefully before you get excited. This is not a loophole for avoiding maintenance. It is a formal route that requires manufacturer training, documented, and full compliance with the operating rule. You become the permitted entity, which means you take on the obligations rather than escaping them.
For an owner who is genuinely hands-on, lives in the house, and is prepared to do the training, it is a real option. For everyone else, it is useful mainly as context: it tells you that the service your maintenance entity performs is defined and teachable, not mysterious.
Whichever route you choose, the hazards do not change. Texas A&M AgriLife Extension’s guide for owners of an aerobic unit and spray field lists what you are working around: disease-causing microorganisms, electrical shock, poisonous or explosive gases, and confined space entry.
What it costs, and why we will not give you one number
Operating permit fees are set locally and published by each county, so the only honest answer is a method rather than a figure.
Two real examples, both for the two-year operating permit: Charlotte County publishes a fee of $200, and Seminole County publishes $150. Those are not a national average or a Florida average. They are two counties, published by those counties, and yours will differ.
Find your own by searching your county health department, or DEP if you are in one of these 17, for its environmental health fee schedule. That document is public, dated, and binding in a way that no estimate on a blog can be. The same method applies to everything else you will pay: our guide to aerobic system installation costs explains how to read a fee schedule and what belongs in a quote.
Separately from the permit, budget for the maintenance contract itself and for the parts that wear out. The aerator is the component most owners meet first: see what happens when the air pump stops working, and our breakdown of yearly maintenance costs.
Florida and Texas, side by side
| Florida | Texas | |
| Ongoing operating permit | Yes, renewed every two years | No equivalent |
| Maintenance contract | For the life of the system | Two years required on new systems |
| Service frequency | At least twice a year | Reporting at least every four months |
| Owner may maintain own system | Yes, as a permitted maintenance entity, with manufacturer training | After two years, for certain system types, subject to local rules |
| Who regulates | DEP, with county health departments acting for it outside the 16 Panhandle counties and Marion County | TCEQ, with local authorised agents |
Related guide. Oklahoma sits in a third category again, and the difference is money rather than paperwork: there is no ongoing operating permit, and the installer is required to maintain the system for two years at no additional cost to the owner. If you are comparing states, or moving between them, see our guide to aerobic septic rules in Oklahoma. This page covers the Florida permit and maintenance entity structure; that one covers Oklahoma’s two-year installer obligation and the 2025 change to who may install a system.
The pattern is the same in both: the state sets a floor, and someone local administers it. What differs is where the obligation bites. In Texas it is the reporting. In Florida it is the permit.
What to do this week
- Work out who regulates you. Check whether your county is one of these 17 DEP counties. If not, your county health department is your office.
- Find your operating permit and check the expiry date. If you cannot find it, ask. An expired permit is easier to fix before someone else notices.
- Confirm your maintenance agreement is current and with a permitted maintenance entity. Ask for the entity’s permit, not just a business card.
- Count the visits. If you are not seeing at least two a year, that does not match the rule.
- Write down the basics. Manufacturer, model, permit number, maintenance entity, last service date. Our component guide helps you identify what you are looking at, and the printable records on our resources page give you somewhere to keep it.
If an alarm is what brought you here rather than paperwork, start with the alarm checklist and deal with the permit afterwards.
Regulations and sources
Educational information only, and not a legal opinion or a diagnosis of your system. Florida’s onsite sewage rules have moved between agencies and rule chapters in recent years: the standards for aerobic treatment units have historically sat in Chapter 64E-6 of the Florida Administrative Code, and onsite sewage standards appear under Chapter 62-6 following the transfer to DEP. Confirm the current citation, the current fees and the current requirements with your own regulator before relying on anything here. Your permit, your approved design and your regulator determine what is required on your property. This site does not encourage tank entry, electrical work, contact with untreated wastewater, or unqualified repairs.
